Description

General part information

IW3689 Series

The iW3689 is a single-stage, high-performance SSL LED driver offering smooth, flicker- and shimmer-free dimming performance and exceptional compatibility with an ultra-wide range of phase-cut dimmers, including the most challenging TRIAC and digital dimmers.

Renesas' patented digital algorithms eliminate more than 20 components, including the external bleeder circuit, enabling integrated active biasing for high-performance dimming at a lower BOM cost compared to conventional bleeder circuits. The iW3689 also works with off-the-shelf inductors to further reduce the BOM.

Full protection features include Renesas' unique over-temperature protection (OTP) derating, which monitors the temperature inside the sealed LED bulb and seamlessly reduces the drive to the LEDs if the temperature rises above a safe operating threshold, it then restores brightness as the temperature falls. The iW3689 integrates the temperature sensor and allows the user to configure the OTP thresholds.
